WINDLASS.

Specification of Letters Patent No. 23,847, dated May 8, 1859.

To all whom 'it may concern:

Be it known that I, DAVID KNowL'roN, of Camden, in the county of IValdoand State of Maine, have invented certain new and useful Improvements inlVindlasses and Wnches; and I do hereby declare that the same aredescribed and represented in the following specifications and drawings.

To enable others skilled in the art to make and use my improvements Iwill proceed to describe their construction and operation referring tothe drawings in which the same letters indicate like parts in each ofthe figures.

Figure l, is an elevation of my improved windlass and winch. Fig. 2, isa plan or top view of the same. Fig. 3, is an elevation of one end.

The nature of my'invention and improvement consists in a winch shaftprovided with barrels and connected to the windlass by gears so arrangedthat the windlass may be worked by the winch shaft, or the winch shaftand barrel may be worked independent of the windlass.

In the accompanying drawings A, represents a portion of the deck of avessel, and B, B, the windlass bitts, and C, the pawl bitt; the wholebeing arranged in the usual position. The windlass barrel D, may be madein the form shown in the drawing, or in such other form as may bepreferred, and tit-ted to turn in the bitts B, B, and provided withratchet teet-h E, for the pawl F, which is hinged to the bitt C, so asto fall into the ratchet teeth, and prevent the windlass barrel fromturning back. The winch shaft Gr, is arranged parallel to the windlassand above it, as shown in Fig. l, and is fitted to turn in the boxes H,H, fastened to the windlass bitts, and in the box H, fastened to thepawl bitt. The. ends of the shaft G, are made square to receive crankslike the one shown at I, by which the shaft may be turned to pull chainsor ropes applied to the winch barrels J, J, which are fastened to theshaft Gr, near each end.

The sockets K, K, are fitted to receive hand spikes or levers to turnthe winch, either alone, or to operate the windlass as may be desired.These sockets are arranged to turn freely on the winch shaft G, and areprovided with pawls one of which is shown by dotted lines at L, Fig. 3.These pawls are arranged to catch the teeth of the ratchet wheels M, M,when the sockets are moved in the direction of the arrow to turn theshaft G, and so as to slip over the teeth of the wheels, when moved inthe opposite direction. The ratchet wheels M, M, are firmly fastened tothe shaft Gr, and winch barrels J, J, so as to turn them. The winchshaft Gr, has the pinion N, fastened to it near the pawl bitt C, whichpinion turns the gear P, fastened to the windlass barrel, to operate itand haul in the cable. The shaft Gr, is arranged to traverse endwise inits boxes, so as to move the pinion N, in, and out of gear endwise, bytraversing the shaft G, which has two collars Q, Q, fastened to it, sothat when the pinion N, is put in gear with the gear P, it may be hldthere by the latch R, and when it is put out of gear, it may be heldout, by t-he latch S; both of which latches are fastened to the bitts B,B.

When the pinion N, is out of gear the winch may be turned either bycranks or hand spikes, or both, entirely independent of the windlasswhich remains stationary. And when it is desirable to use the windlass,the pinion N, may be put into gear with the gear wheel P, so as to turnthe windlass either by the winch cranks or hand spikes,

or both as may be desired, and according to the power to be exerted.

By arranging the winch upon the windlass bitts it is more out of theway, than if it was applied to any other part of the vessel; besides itcosts far less to apply it to the bitts than it would to erect standardson purpose to support it. And by arranging it on the bitts above thewindlass,it is so near the windlass, that I am enabled to connect thewinch to the windlass, by a pinion and gear wheel, thereby making ageared windlass of great power, at a very small expense. And at the sametime have a windlass that can be Voperated slowly with great power byapplying hand spikes to the sockets; or operated quickly with less powerby turning the cranks: being admirably adapted to get an anchor upquick, so as to enable a vessel to escape squalls or bad weather.

I believe I have described and represented my improvements in windlassand winch s0 l as to enable any person skilled in the art to shaft, 0rthe Winch shaft and barrels, may make and use them. I will now statewhat be Worked independent of the Windlase, sub- I desire to secure byLetters Patent to wit: stantinlly as and for the purpose descrlbed. 10

I claim the Winch Shaft Gr, provided with DAVID KNOWLTON. 5 barrels J,J, and connected to the wndlass TWitnesses: fl

by gears as described, and so arranged that I. DENNIS, JL', the Windlassmay be Worked by the winch EDW. F. BROWN.
